Yesterday, I woke up and my knee hurt. I didn't do anything to make it that way, it just hurt. Okay, I can deal with that. Today, I woke up and my knee is swollen and I can hardly stand on it without excrutiating pain. I threw a tensor on it and went to work, which makes it so I can stand, but still hurts if I sit too long. I have no idea how this happened. Tomorrow, my leg will either fall off or I will be fine.
